1. What are Arithmetic Operators?<\/h2>\n

Arithmetic operators<\/strong> are used to do math calculations<\/strong> in Python.<\/p>\n

We use them to:<\/p>\n

    \n
  • \n

    Add numbers<\/p>\n<\/li>\n

  • \n

    Subtract numbers<\/p>\n<\/li>\n

  • \n

    Multiply numbers<\/p>\n<\/li>\n

  • \n

    Divide numbers<\/p>\n<\/li>\n<\/ul>\n

      \nprint<\/span>(\"Cube:\"<\/span>, num ** 3<\/span>)
      \n<\/code><\/div>\n<\/div>\n

      Example 3: Even or Odd<\/h3>\n
      \n
      \n
      \n
      <\/div>\n<\/div>\n<\/div>\n
      num = 7<\/span><\/p>\n

      if<\/span> num % 2<\/span> == 0<\/span>:
      \n print<\/span>(\"Even\"<\/span>)
      \nelse<\/span>:
      \n print<\/span>(\"Odd\"<\/span>)
      \n<\/code><\/div>\n<\/div>\n

      14. Summary (Arithmetic Operators)<\/h2>\n

      \u2714 Used for math
      \u2714 + - * \/<\/code> are basic
      \u2714 %<\/code> gives remainder
      \u2714 **<\/code> gives power
      \u2714 \/\/<\/code> removes decimal<\/p>\n
